However, when we call the function with x=2 and y=0, a ZeroDivisionError occurs, and Python raises an error message indicating that division by zero is not allowed. When a function throws an exception that it does not handle itself, it is making the assumption that a function up the call stack will handle the exception. This tutorial will focus on how to handle unknown exceptions and print that in C++. The stack will be unwound in an orderly manner (ensuring destruction of local variables).
